The absolute frequency of the f-component for the UME laser was measured with the BIPM femtosecond laser comb to be (473 612 353 602.0 ± 1.1) kHz during 3 March to 8 March, 2003 and with the UME comb to be (473 612 353 600.6 ± 1.1) kHz from 20 June to 25 June, 2005. After appropriate correction for power and modulation shifts a subkilohertz agreement between the two measurements was found. Moreover, the relative frequency stability for different UME–BIPM laser pairs is investigated using standard heterodyne techniques and Allan variance statistics.

Abstract
The absolute frequency of the f-component for the UME laser was measured with the BIPM femtosecond laser comb to be (473 612 353 602.0 ± 1.1) kHz during 3 March to 8 March, 2003 and with the UME comb to be (473 612 353 600.6 ± 1.1) kHz from 20 June to 25 June, 2005. After appropriate correction for power and modulation shifts a subkilohertz agreement between the two measurements was found. Moreover, the relative frequency stability for different UME–BIPM laser pairs is investigated using standard heterodyne techniques and Allan variance statistics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
